In the semifinal, Elizabeth Moon lost on the 19th hole because Erika Shepherd did not concede a 6 inch putt to her when Moon thought she did and picked up too early. I first thought both were to blame, Moon for anticipating the concession and Shepherd for not conceding the putt. Then saw the video where Shepherd walks away like she is conceding then turns around and calls out Moon. Shepherd is going to Duke by the way, not that that should influence your opinion on sportsmanship. The important part of the video starts at 1:55.
